Google's energy use

You may recall the story about a Google search generating as much CO2 as boiling a kettle for a cup of tea. As we reported here, it turned out to be more of a storm in a tea cup.

Now, though, in a blog by Urs Hölzle, Senior Vice President, Operations, Google has supplied some comparisons of the emissions from everyday activities compared with the equivalent number of Google searches. Chapter and verse is here, but summarised in the chart below.

The blog goes on to say that Google's efforts to cut its energy use means that " the time it takes to do a Google search, your own personal computer will likely use more energy than we will use to answer your query". So now it's your turn.
